Alternatives would be nice, but what the OP did was give examples of why they felt it was broken, which is useful. The perspective of someone dropping into the content and what they felt and their point of view is a valuable resource for someone planning content changes or even future content. Sure we can "educate" them on the best way to do it or the proper way to do it, but telling them their experience was invalid and they're foolish helps very little.
The content is 2 weeks old, the "zerg" is still spanning a decent amount of levels and there will always be a few charitable people in a group trying out new content. Future populations will tend to be far more spread apart level wise and likely limited to people doing the relic grind only, I hope people are there to help, but it will depend on them being charitable for charities sake, something I will not bet money on. This is something I really hope I'm wrong about.
You can bet money that players will always, ALWAYS find the easiest way to do content and then the majority will only do that until the content is spent or changed (see "loot cave" from destiny) . Expecting them not to is setting your system up for failure. Feedback like what we don't enjoy and what we think doesn't work. I don't think incentives are the ONLY way to encourage people to assist underlevels but it's probably the easiest to add and path of least resistance has been the norm. Can you honestly say If I ran an alt and asked people to party up and do the mob chain and only invite people near our level as the content seems to intend.. I'd not be looking a very long while?
